Native and Non-Native Fish Species in the Willamette River Basin, Oregon The Willamette River Basin, Oregon, supports native fish species and non-native fish species introduced for sport fisheries or accidentally from aquarium releases and other sources.

Each native and non-native fish species has its own thermal tolerances and diet, spawning, and vertical preference traits. This means that distributions of native and non-native fishes along the river network are shaped by physical factors...
